[Zope] referencing title value as a var name

[Tino Wildenhain]

Hi Kerekes,

I think using a DTML document only as container
for a single string to look up is a bit overworked ;)
What about a single lines Property with the words you
want int the given order and then:

<dtml-var expr="StateProperty[STATE]">

This will work with integer as lookup.

Regards
Tino
